I have many wildcat cartridges, so I often find myself loading outside the box... & trying to figure out which powders to use... I think I have a good grasp of this, until I start seeing some data posted on line, & often these look like "the best power" was chosen from the 4-6 powders the loader had to choose from I'm trying to learn as much as I can why certain powders are chosen in both factory & wildcat loadings, aside from "it's what I already had on hand"... burn rates, powder fill densities, energy if that is even possible... I found this site that has a video comparing a fast burning powder to a slow burning powder, that's kind of cool to watch... www.wideners.com/smokeless-powder-guide#physical-characteristicsyou guys have any particularly interesting places to learn more about loading powders you can link here??? or care to discuss further |

There is a best powder for the pressure/velocity range you want. Most of the time it's in an older manual. Sometimes new is good and sometimes it isn't. Currently, I'm using the 50 cal / 20mm surplus powders in some very unusual ways. My best advice is if some powder isn't working out, dump it and try another close to it in burning range. Like powders DO NOT give the same results and vary immensely in different cartridge shapes, calibers and capacity.

I'm is kind of a similar but different conundrum.
There used to be data printed in load manuals for pushing a 300 gr .416 bullet over 2900 fps from a 416 Rem mag. However, I can't find a current manual that lists any of the old loads. They worked in my last 416 Rem .
But now it seems all loads are being soft peddled.
When I think about it too much my head starts to spin out and I get really cranky.
Questions like , WHY did Hodgdon stop their data where they did, leaving a few thousand psi on the table with their H4895 loading with the 300 gr TSX bullet.
Does anyone have the newest Lee loading manual ?
If they do could they send me a pm or we could discuss it here if that's alright ?

I tend to choose a powder based on lower pressure it generates to hit a certain velocity compared to the other powders. After pressure I look at case fill to be over 50%. I like stable powders with straight line performance rather than erratic or spiky. Small, accurate, tiny groups at distance are my goal.
I use a lot of 4227, N340, HS-6, 231, and TrailBoss. I like TiteGroup, Bullseye, and H110; just not as well.
Prescut
Great question. I have had to use many sources and build my own paper on differences in the powders. It's mostly opinions, myths, and lore. Getting experience can be expensive and time consuming. Let us know what you find.

I have the newest lee loading manual. What do you need?

What is the fastest 2 loads they show for the 416 Remington magnum 300 grain bullet.
How many gr of what powder. Velocity and pressure
Seems every tom dick and harry lists plenty of loads for the 350 and 400 gr bullets . Even Barnes isn't listing load data for the 300 gr bullets.
People are really missing out !
Everyone thinks big bore rifles need heavy bullets.
Big bores need GOOD , Tough bullets. And high velocity. At least for Alaska. In my opinion.
Not that heavy bullets don't work.
But why shoot a heavy when the light weights work So well.
Any info will be very much appreciated !
Thank you !
Glen.

Barnes may not list it, but call. My young friend with the Henry 45-70 bought some Barnes all copper bullets and we were coming up short on data. A phone call got us a pet load using a VV powder that is pretty wicked WAY out thar ! Luck.

Wheelguns helped me out with the Lee #2 manual.
I can't figure out why the data for the 300 gr Barnes TSX, H 4895 has been detuned by 5.5 grains.
I've shot a bunch of the 300 gr bullets in previous 416 Rem rifles at around 86 gr. It was a good load.
But it does mean I need to pull down a bunch of ammo and work up for my new rifle.

I think it would be quite nice if those that write manuals would give explanations as to why the data gets changed.

In all fairness to those putting together the manuals... Maybe they now have better pressure testing... Awe.. Nevermind... Probably just the lawyers

What gets me whound up. Is weather it's a case of actual pressure problems.
Or that some gob thinks I don't have any use for a 300 gr bullet going over 2900 fps out of a 416.
That , in my opinion is what mono metal expanding bullets were made for.
Like a 300 gr X or TSX in 458 @ 2700 + fps.
These loads blow fist size holes thru bears.
But, I don't want to strain the receiver on my rifle.

Currently, I'm using the 50 cal / 20mm surplus powders in some very unusual ways. ^^^This... anyone using rifle powders to achieve mid-range loads in magnum handgun cartridges with near 100% load density? Been interested since John Ross posted on the topic but have not delved into it. |

I think it's a good idea, but then I don't know a ton of stuff about the rocket science propulsion facts and figures. I don't see any reason I couldn't load large revolver cases with rifle powder to get less pressure and velocity.  Its a really good question. |
